Magnus and me shared Microservice drawbacks and our reflections to work around those. We got so many great questions from the audience that triggered fruitful conversations that we barely finished the talk in time 😉 .

This talk is so interesting, the questions are numerous and answered during the presentation. So there are only 15 mins left and speakers are only halfway there !#DevOpsCon

Deploy Kotlin applications instantly to Kubernetes cluster within seconds and without Dockerfiles. Slides are in German.

CI/CD with GitHub Actions including firebase functions deployments and a live demo to deploy Docker image to Dockerhub and GitHub Container Registry.

I gave a talk in German about:
Docker Image deployments to Dockerhub and GitHub Container Registry with GitHub Actions including a live demo with open source code you can also use.

Tech Alignment with Narratives.

What are Narratives and why should you use those.

Addressing the most frequent pitfalls when transitioning to Microservices.

Magnus and me talked about microservice drawbacks we experienced and shared how to deal with those.

In this talk I shared and showcase how to implement a CI/CD pipeline with open source GitHub action components. The audience may use the presented open source examples to build their own CI/CD pipelines based on open source GitHub action components.

GitHub Actions Continuous Delivery 101 slide deck

Deploy Ktor applications instantly to Kubernetes – in this case EKS on AWS – without Dockerfiles. A showcase how to create docker images with kotlin, gradle and jib. The docker image is pushed instantly to ECR on AWS. Afterwards the updated docker image is deployed to the EKS cluster on AWS. Kubernetes uses the updated docker image and rolls the deployment.

Kotlin, ktor, gradle, jib, skaffold, kubernetes (EKS) rock 😉

An online workshop about How to align tech teams with​ Narratives in German. The participants did create their first narrative based on the input I presented. Slide Deck download.

How to CI/CD with GitHub actions is the main subject of this talk. I shared also first experiences with self hosted runners. Slide Deck download.

Deploy Ktor applications instantly to Kubernetes without Dockerfiles. In this talk I shared how to create docker images with gradle and kotlin only. Also I deployed the docker image to a Kubernetes cluster almost instantly.

Alignment in Tech organisations in particular between Product and Software engineers can be challenging. There are traditional agile approaches like user stories and storytelling. In this talk I shared an additional approach that was recently adopted at Moovel not only in Product and Software Engineering but also in other squads: ​ Narratives.

It was great to join a panel discussion about open source & security.

My talk outlined options how to reduce docker images with respect to: docker image size and attack surface.

In this talk, I described interfaces my teams considered and implemented when building a CI/CD solution.

Docker image journey – How to shrink a docker image

In this talk, Rasha Malek and I described how the source code engineering team successfully supported the voluntary adoption of GitHub Enterprise and still managed around 100 new seats every month. Here we talked about the advantages and disadvantages of this approach and share insights about the initiatives that were triggered by Github Enterprise at ZalandoTech. We also shared the challenges we came across.

I communicated the team’s approach to meet the CI/CD requirements we faced at that time. Based on these requirements, we implemented a CI/CD server infrastructure. This enabled us to fulfil the requirements as well as streamline the solution for the cloud and cluster environments.

I did participate in a panel discussion about Modernizing Software Architecture.

I presented options how to expose Kubernetes services with loadbalancers and ingress.

In this keynote, I described how the team I served successfully moved from a central, continuous integration infrastructure to a distributed infrastructure. I explained how the team leveraged its existing expertise to develop the first version of its new landscape, and discussed alternative plans the team considered before adopting this approach. I shared insights about CloudLobster & CloudKraken, Zalando’s APIs for creating and managing CI instances & agents. Throughout this talk, I talked about issues we encountered along the way and how this team solved and worked around them. I explained why a distributed approach to continuous integration made sense at that time.

Scaling Continuous Delivery at Zalando with CI server pipelines was the subject of this talk.
